Is there a way to import Python 3 modules into Python 2 scripts? I want to use some Python 3 modules in a Django application and haven't seen anything on the Internet. Any clues?

Python 2 and Python 3 were never intended to be compatible internally. In fact, the reason Python 3 exists was to be able to make incompatible changes that would not normally be made in a minor version update, e.g. 2.6 to 2.7. This includes byte codes which may not be compatible even across minor versions.
The latest stable version is Python 3.9 which was released in 2020. The nature of python 3 is that the changes made in python 3 make it incompatible with python 2. So it is backward incompatible and code written in python 3 will not work on python 2 without modifications.
Modules can import each other cyclically, but there's a catch. In the simple case, it should work by moving the import statements to the bottom of the file or not using the from syntax.
I don't think it's really possible, no. The same instance of the interpreter has to handle every module imported in a given app, so there's no obvious way to mix and match interpreters. If you need to accomplish a discrete task with a Python 3 module, you could try making a command-line script to accomplish your task and then calling that script as a subprocess from your Python 2 app, but that would be awkward to say the least.
Note that I don't think there are really a whole lot of Python 3-only modules -- most modules at this point either support both versions, or only Python 2.
